ReferenceDiagnosis
R. G. Johnson 2024Cephalon widest at eye lobes. Muscle attachment scars on glabella visible at S2, S3 and S4 barely reaching out of axial furrow. Alae well-defined and with alar furrow and ridge. Eye lobes close to inner margin of fringe; eye ridge and genal ridge present and inner margin of fringe concave across the anterior of genal areas. Genal roll sloping anteriorly moderately steeply (just under 600) down to narrow girder with prominent oval recesses beneath, formed by caecal ridges radiating down from girder. Brim wide (sag.) (between 25% and 38% of cephalic length (sag.)), external rim narrow (less than 10% of width (sag.) of brim). In lateral view, internal rim is straight and slopes down posteriorly at a shallow angle.
